STOP AND WASTE COCK.

SPECIFICATION forming part Aof Letters Patent No. 569,967, dated October20, 1896.

Application filed January 3l, 1896.

T a/ZZ whom t may concer/Z:

Be it known that I, SAMUEL M. FRIEDE, of Chicago, Cook county, Illinois,have invented a certain new and useful Improvement in Stop and WasteCocks, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to an improvement i'n stop and waste cocksforwater-service pipes, the object of the invention being to provide adevice of the kind of a simple and efficient construction that can bereadily attached to the side of the service pipe at any point throughoutits length without cutting the pipe in two and forming wiped joints, asis the prevailing custom in attaching such cocks to the pipes.

My invention consists in features of novelty hereinafter fully describedand pointed out in the claims.

Referring to the drawings, Figure I illustrates a side elevation of myimproved stop and waste cock, in which view the handle of the valve-plugis shown removed, on a section-line II, Fig. II. Fig. II is a frontelevation of the device. Fig. III illustrates a vertical section takenon line III III, Fig. II. Fig. IV illustrates a horizontal section takenon line IV IV, Fig. II. Fig. V illustrates a horizontal section taken online V V, Fig. II.

In the drawings, Ldesignates a soft-metal pipe, such as lead, and as iscommonly used for water service. In one side of this pipe I form threeopenings 2, 3, and 4.

5 designates the rear member of the cockhousing, and 6 the front memberthereof. In the front member 6 is a lower inlet-port 7 and an upperoutlet-port 8, and extending from the inlet to the outlet port is achannel 9, the central portion of which is of circular formation, and isdesigned to receive the valveplug 10, provided with aV handle 11. Thevalve-plug IO is provided with a chamber 12, and at opposite sides ofthe chamber are openings 13, through which the water passes during theordinary iiow of water through the service-pipe. At a mid-distancebetween the openings 13 is an opening 14, through which the waste wateris drained to a small dis charge-pipe 15, located in the front of theSerial No. 577,510. (No model.)

member 6 of the cock-housing. 16 designates tubes inserted in theopenings 2 and 1I in the side of the pipe l and extend into the ports 7and S for the purpose of providing 55 connection between the pipe andsaidports.

17 designates a protuberance on vthe back of the lnember 6, and which iscovered with a bushing I8, that Afits the opening 3 in the pipe 1. Thisbushing 18 is designed to close 6o the pipe at the point of itsinsertion, thus preventing the iiow of water through the pipe andcausing it to take the course through the ports 7 and 8 in its ascentand in the action of draining the water from above through the port 8 todischarge-pipe 15.

Interposed between the member 6 and the pipe I is a packing I9, whichenables a tight joint to be formed between the members of the pipe andalsov around the tubes 16. The 7o two members of the housing areconnected together by means of screws 2O or other suitable fastenings.

In forming the openings in the sides of the pipe 1 it is important thatthey be spaced 75 proper distances apart, and vfor this purpose I formon the interior of the surface of the pipe and member 5 of the housingthree points 5, located at distances apart corresponding to the openings2, 3, and 4to be formed in the 8o side of the pipe, and before makingthe openings 2, 3, and 4 I press the member 5 against the pipe, and thepoints 5fL mark the proper location at which the openings are to be madein the pipe. l

I claim as my invention l. In a stop and waste cock, the combination oftwo housing members adapted for attachment to a pipe provided withopenings in its side, one of said members being provided 9o with portscommunicating with the openings in said pipe and with a channel forminga communication between said ports, and a valve-plug located in saidchannel, substantially as described.

2. In a stop and waste cock, the combination of the two housing membersadapted for attachment to a pipe provided with openings in its side, oneof said members being provided with ports communicating with theopenings roo in said pipe and with a channel forming a communicationbetween said ports, a valveplug located in said channel, and a dischargepipe leading from said channel, said plug provided with openingsarranged to form communication between said ports o1' between either ofthem and said discharge-pipe, substantially as described.

In a stop and waste cock, the combination of two housing members adaptedfor attachment to a pipe provided with openings in its side, one of saidmembers earryin g an elastic bushing arranged to be inserted through thecentral one of said openings for the purpose of closing communicationthrough the pipe, said member being provided with ports communicatingwith the two other openings in said pipe, and with a channel formingcommunication between said ports, and a valveplu g located in saidchannel, substantially as described.

4. In a stop and waste cock, the combination of two housing membersadapted for attachment to a pipe provided with openings in its side, oneof said members being provided with ports communicating with theopenings in said pipe, and with a channel forming a communicationbetween said ports, a valveplug located in said channel, and tubes 1Gconnecting the interior of said pipe with said ports, substantially asdescribed.

5. In a stop and waste cock, the combination of two housing' membersadapted for attachment to a pipe provided with openings in its side, oneof said members being provided with ports communicating' with theopenings in said pipe, and means carried by said 'member arranged toclose the passage-way through said pipe between said openings, saidmember being also provided with a channel forming a communicationbetween said ports, a valve-plug located in said channel adischarge-pipe leading from said channel, said valve-plug being providedwith openings arranged to form communication between said 4ports orbetween either Vf them and said discharge-pipe, substantially asdescribed.
